-x + 4 = -7
(take away 4 from both sides of the equation)
-x = -11
(times both sides by -1)
x = 11
(-11 + 4 = -7)
If: 7+t = 11 Then: t = 11-7 So: t = 4
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
3x+4 = 2x-3 3x-2x = -3-4 x = -7
n= -2
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
If: 7+t = 11 Then: t = 11-7 So: t = 4
x=4 y=x+3 y=4+3 y=7
2x+3 = 7 2x = 7-3 2x = 4 x = 2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
3x+4 = 2x-3 3x-2x = -3-4 x = -7
n= -2
To solve the expression 5 plus 7 (4-3), first calculate the parentheses: 4-3 equals 1. Then, multiply 7 by 1, which gives you 7. Finally, add 5 plus 7, resulting in 12. Therefore, the answer is 12.
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
p is obviously zero because any number x plus 0 equals itself.
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
x=7
